3.3.3

• Fix d3.mouse for touch events with no touches (such as touchend).
• Fix d3.behavior.zoom when a secondary touch is started outside the zoomable element.
• Support parsing time zone offsets (%Z) in d3.time.format.

3.3.2

• Fixes crash in d3.transition on IE9 due to lack of ​_​_​​proto​_​_ support.

3.3.1

• Fix obsolete “major” class being inadvertently applied to axis ticks.
• Fix floating point precision bug in d3.geo.circle causing an occasional coincident endpoint.
• Fix d3.time.format parse to ignore optional padding specifiers (e.g., “%-d”).

3.3 “Haleakalā”

• Add selection.interrupt for immediately interrupting the current transition.
• Add brush.event for programmatic brushing, including transitions (e.g., 1 2).
• Add zoom.event for programmatic zooming, including transitions (e.g., 1 2 3 4 5).
• Add d3.interpolateZoom for smooth zooming based on van Wijk & Nuij (e.g., 1 2).
• Add zoom.center to control over focal point while mousewheel zooming (e.g., 1).
• Add “zoomstart” and “zoomend” events to zoom.on.
• Add d3.geo.transform to simplify creating custom geometry transforms (e.g., 1 2).
• Add d3.geo.clipExtent for viewport clipping with custom transforms (e.g., 1).
• Allow d3.geo.stream to stream three-dimensional coordinates; useful for dynamic simplification.
• Add “beforesend” event to xhr.on to manipulate the request before sending.
• Add axis.innerTickSize and axis.outerTickSize; deprecates multi-argument axis.tickSize.
• Add d3.pairs for constructing tuples of adjacent elements.
• On quantitative scales, including time scales, scale.ticks() is now equivalent to scale.ticks(10).
• On quantitative scales, including time scales, scale.nice() is now equivalent to scale.nice(10).
• On time scales, scale.nice(count) and scale.nice(interval, skip) are now supported.
• On time scales, scale.ticks(interval) is now favored over scale.ticks(range).
• Fix transition “end” events such that they are fired before transition cleanup, for easier chaining.
• Fix transition submillisecond timing to improve synchronization of long-running transition chains.
• Fix subpixel-precision brush extent when set programmatically.
• Disable axis.tickSubdivide; use post-selection and multiple axes instead.
• Disable webkit-tap-highlight-color when using the brush.
• Escape non-ascii character in d3.v3.min.js.

3.2.8

• Fix multitouch handling in d3.behavior.zoom and drag-based interaction.
• Fix d3.map copy constructor for objects that implement array.forEach.
• Fix crash in selection.sort when the selection has multiple null nodes.
• Fix crash in tick generation for d3.scale.log with invalid domains that span zero.
• Several micro-optimizations.

3.2.7

• Color interpolators (and by extension, quantitative scales) once again return strings rather than color instances, improving performance and lessening surprise. (Partially reverts 3.2.4.)
• Fix transition chaining such that earlier transitions are guaranteed to end normally (emitting end events) before later transitions start.
• Fix crash in transition.filter with empty transitions.
• Fix zoom behavior on devices that support touch and mouse events simultaneously.

3.2.6

• Fix bug in log.nice introduced in 3.2.5.

3.2.5

• Fix bug with localized decimal point in d3.format.
• Fix default behavior suppression for drag gestures (e.g., d3.behavior.zoom) on touch devices.
• Suppress double-tap default behavior with d3.behavior.zoom on touch devices.
• Improve floating point precision for log.ticks and log.nice.
• Include minified JavaScript for use with Bower.

3.2.4

• Add currency support to d3.format (e.g., "+$,.2f").
• Add missing quantile.invertExtent method.
• Fix enter.insert to preserve order of entering elements relative to updating elements when no before selector is specified. This provides a more efficient alternative to selection.order in cases where the updating selection is not reordered.
• Fix “basis” line interpolation for WebKit marker automatic orientation.
• Fix transition.each to inherit transition.time, precisely synchronizing chained transitions.
• Improve transition performance by lazily constructing "start" and "end" event dispatcher.
• Change d3.interpolateRgb and related methods (including d3.interpolate and d3.scale.linear) to return color instances (e.g., d3.rgb) rather than hexadecimal strings. Reverted in 3.2.7.

3.2.3

• Allow pack.radius to be specified as a constant.
• Accept a function for selection.append and selection.insert.
• Limit automatic transform interpolation to transition.attr.
• Fix polygon.clip for closed polygons.
• Build fixes for Bower and Component(1).
